Interface ImageOperations

All Known Implementing Classes:

AWTImageOperations, SWTImageOperations

public interface ImageOperations

The ImageOperations interface defines an object that is used by the Graphics API to perform operations upon images.

This layer of abstraction is needed by the Graphics API in order to be able to work with different window toolkits like the AWT or SWT.

Encodes the given pixel data to JPEG data.

Parameters:

width - The width of the image

height - The height of the image

pixels - The pixel array width a size of width*height containing the colors encoded as 0xRRGGBB

quality - The JPEG quality (0.0f - 1.0f)

forceBaseline - The force baseline setting for the JPEG encoder

Returns:

The bytes of the JPEG file
